I don't know many books that deals 100% with cosmic rays. Books in high energy astrophysics and particle astrophysics often deal with Cosmic rays (also some books in nuclear astrophysics). You should try get a new one as possible. I have a lot of books, and maybe you can find something about cosmic rays just by googling.
But I can't "recommend" them since I have not studied them, I only have studied cosmic rays from hand out materials and chapters in astrophysics, particle astrophysics and nuclear astrophysics textbooks.
